Shower grab handle tray

This is a openSCAD design to create an accessory that attaches to the grab handle in the cruise ship shower.

The tray stores things normally on the floor and it also has a loop to hang a razor.
There are scad "lists" for mount and tray versions.

All/most variables are global and should be easy to customize.

There are two scad files one for generating trays the other for the mount part. They are interconnected with a shared dovetail.

20mm grab handle

As found on Grand Princess and Discovery Princess
I expect it is a pretty standard grab handle.

25x50mm shower handle pole

As found on Discovery Princess

25mm grab handle

not found on cruise ships yet but sort of standard.

32.5mm curved shower handle pole

as found on Discovery Princess wheelchair cabins

easy to customize

and add other mounts as they are measured

current tray versions

soap dish

ridges to help soap dry

small holder

Holds small/travel bottles of products

large holder

This needes a large printer

modular trays small soap loop

That can be plugged together multiple ways

also easy to add other sizes

Prototype history/log

first version test.
A single part. This was for the curved handle found on all the ships so far. I had to guess on the diameter and made it too big so it was rather sloppy and I had to heat it up to make it work. Learned that it was 20mm not ~1 inch.

second version test.
New 20mm mount that worked but too fat and tall. needs to be smaller. The razor loop needs to be enlarged.

third version test.
Still a single part. Version fits nice. A little leaning due to "curve" elongating the lower clamp. This ship has more places for storage and the shower is on a 25mm pole on a 50mm pole.

forth version test. now connecting mounts to trays with a dovetail two mounts: 20mm and 25x50mm. two trays a "small" and a "soap"
mount 20mm with "soap" tray
mount 25x50mm with "small" tray
All worked fine noticed that trays could be adjusted about 2 degrees up they would level out. Soap dish worked fine but needs ribs for drying.

fifth version test.
"Tee" post test. the first cabin was assisted care with a different bathroom. It needed a 25mm curved mount.Second cabin tested the "Tee" post mount. It worked ok but a bit large.dovetails need tightening. 

sixth version test.
Quite saggy, mount needs improvement, also when all is assembled it is a bit too long.  the product tray is too narrow and should be made shorter and wider.  Soap dish needs loops on the sides.
